Abstract

WE have previously studied the chemical changes produced by radiation in aqueous solutions and especially the use of such changes for radiation ‘dosimetry’, that is, the measurement of the energy absorption of ionizing radiations1. In the search for a suitable system which would enable three-dimensional distributions of absorbed energy to be demonstrated, we have experimented with gels containing dyes which are reduced with change of colour on irradiation. Various phenomena have been observed, apparently bearing also on the biological action of ionizing radiation and perhaps on electron-capture processes in general.
